Wonder whether he actually mentioned carprofen injections Ginny - they are a longer working NSAID thats an alternative to rimadyl etc. They give the dogs I think 3-4 injections on a weekly schedule and they can last for around 6 months I think. I've only heard it being used when the dogs are persistently limping through the arthritis tho and would look at other supplements as Elaine mentioned to help support her, also green-lipped mussel... Dorwest Herbs do a good selection of supplements to support joint issues. And take a look at the use of turmeric powder as well - that's another natural supplement a lot of folks use to reduce effects of arthritis. (There's a group on facebook if you're on there called Turmeric Users Group - very good with loads of information on how to administer it etc) As yet Maggie hasn't had to take any NSAIDs since her operation but I know it will happen at some point.
Again good advise from Elaine about the slippy floors, avoid any jumping ideally but especially down from things as that will jar her elbow (I've had that conversation with Maggie many times...!)
Its really hard. When I finished with Maggie at the specialists they were adamant no jumping, running high speed, chasing balls where she might twist and stop quickly.... but I have to let her live her life. So I'm sensible for her, will make her stay in if I think she's had a big/strenuous walk the day before etc but I don't restrict her much. She needs to be happy and I know she wouldn't be if I left her on a lead the whole time.
